The recovery of gold at Stawell Gold Mine can be improved by using cyanide and thiocyanate free water in the milling process. The aim of this research is the development of a novel separation technology for the removal of these two ions from mine wastewater to allow it to be recycled. Novel polymeric materials, known as polymer inclusion membranes (PIMs), which have never been used before in industrial separation, will be at the centre of this technology. In addition to increasing gold recovery, this technology is expected to reduce substantially the reliance of the Australian goldmining industry on fresh water. This research will also promote PIM based separation as a viable industrial separation technology, applicable in other areas.

在铣削过程中，可以使用氰化物和无硫氰酸酯的水来改善黄金矿的回收。这项研究的目的是开发一种新型的分离技术，以从矿水废水中去除这两种离子以允许其回收。新型的聚合物材料（称为聚合物包容膜（PIM））将是该技术的中心。除了增加黄金恢复外，这项技术有望大大减少澳大利亚黄金行业对淡水的依赖。这项研究还将促进基于PIM的分离作为可行的工业分离技术，适用于其他领域。
